| 摘 要： | 为了描述和分析在夏季使用分体落地式空调器来制冷的办公室室内的气流组织,根据实际情况建立其物理和数学模型,应用CFD方法对办公室空调房间上送下回的送风方式下的气流组织进行三维数值模拟。通过Fluent软件来进行数值解算,给出室内速度场和温度场的分布状况。通过对不同空间位置的速度矢量图和温度等值线图的分析,得到了该室内气流组织的合理性和人员所处不同区域的热舒适性,并以此来指导办公室内空调通风的设计和改进。

| Abstract: | The indoor airflow distribution is described and analyzed in office when people use the split and console model air-conditioner to cool air. The relative physical and mathematical are established. Based on the CFD method, 3D numerical calculation is used to simulate the airflow distribution at the air supply pattern of that air sent from the top and returned from the bottom of the room. Air velocity field and air temperature field be simulated by Fluent software are presented. The velocity vectors and the contour maps of temperature are analyzed. Rationality of indoor airflow distribution and thermal comfort of persons in different areas are achieved which are used to instruct the design and improvement of air-conditioning and ventilation in the office. |
